Very nice.I used Ricotta rather than Cottage Cheese because I have a couple of things I can do with that (ricotta creme dessert) and I rarely eat up leftover cottage cheese.
I used greek yogurt instead of sour cream.
With both of those substitutions I think it could have used a tad more moisture, but it was still quite good.
I cut the recipe in half and if I did it again I'd do like MC and put in the whole cup of shredded cheese, but all I had was 1/2 a cup anyways.
I put breadcrumbs and some artificial bacon bits I have on the top and with the paprika that made a nice crust on the top.
